Abstract: An apparatus and process for continuously and endlessly vulcanizing a hose is disclosed and claimed. Pressurized air or other gas is intermittently supplied through a woven jacket, a mandrel, a check valve and into the interior of an extruded rubber hose. The hose is sealed as it is pulled over the mandrel. Pinch rollers seal the other end of the hose. One or more non-contact heaters vulcanize the hose from outside-in. Pressurizing the inside of the hose maintains proper diametrical dimensions of the hose.

Abstract: An improved polyurethane derived resin for casting, pultrusion and lamination purposes particularly fibreglass lamination purposes. The resin is produced from the reaction of an isocyanate compound with an hydroxylated acrylic and a polyol. Photoinitators may be included in the resin to allow effective curing under ultra violet light.
